DRY-SUITS

Mar

In simple terms, there are 2 types of dry-suit: the membrane dry-suit and the neoprene dry-suit.  There are a few variants with crushed neoprene, which behaves like a membrane suit, but for simplicity I shall only refer these 2 types.

BACKPLATE & WING VS STAB JACKET

Mar
04

The vast majority of recreational divers use stability jackets (“stabs”/BCD) and “wing” type buoyancy aids are relatively rare.  Ten or so years ago stabs were relatively rare and most UK divers used the ABLJ (Adjustable Buoyancy Life Jacket).  The stab gradually replaced the ABLJ as divers realised that the stab was more comfortable and cleared the chest area of the annoying “horse-collar”.  The same is now true of the comparison between a wing and a stab.

LONG HOSE VS STANDARD OCTOPUS

Jan

Is the “standard” way of using a 2nd stage regulator on a normal length hose plus an “octopus” regulator on a slightly longer hose the best way to arrange things?  Have you just taken this for granted and not given it any serious thought? Using this system the diver breathes from his primary regulator (on a normal length hose) and stows the “octopus” about his person somewhere.

HOGARTHIAN (DIR) DIVING EQUIPMENT GUIDELINES

Jan
09

The following guidelines are aimed at ALL levels of divers, from those just beginning to those people who have dived for many years. If you doubt this, spend some time reading the section discussing the long hose and those references made to the use of a small wing with harness and single tank adapter. The cost of much of the equipment that I am recommending is the same as much of the “normal” gear. Bear in mind also that it won’t become obsolete/inadequate if, at a later date, your needs change as you venture into more advanced diving. I have learnt this lesson the hard way! Even if you never intend to get into such diving, you are diving a more thoroughly thought out and safer system in the meantime.

DIR Equipment Configuration

Dec
02

 "The DIR equipment configuration tends to generate the majority of interest and debate, initiating the common misconception that one part of the system can be adapted and others can be ignored. For example, individuals may endorse the equipment configuration, but ignore essential aspects such as the team-centered approach or physical fitness. DIR is a holistic system and although incorporating parts of DIR into another system is possible, the result is not DIR. The mutation is also likely to be fraught with complications.
